CONDUIT OR BRACKET FOR CABLE RAILWAYS.

SPECIFICATION forming part. of Letters Patent No. 364,499, dated June 7*, 1887.

Application filed September 3, 1886. Serial N T aZZ whom, it may concern.-

Be it known that I, EDWARD D. Docen- ERTY, of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented acertain new and useful Improvement in Conduits or Brackets for Cable Railways;

strengthen the bracket that supports the sec tions of conduit-pipe and holds them in axial line, so that the weight of the tube and superincumbent mass of earth over same, when in position, will be prevented from spreading the bracket, and also give necessary rigidity to resist the destructive influence of frost; further, to provide, intact with the bracketbody, adequate means for relieving the conduit-pipe at these points of surface-water that is flushed in through the slot of the center platein which the grip-bar slides; in conjunction with and assisting to effect these desirable features to provide. integral with the bracket a suitable support for the pulleywheels, and so permit them to be held in position independent of the sections. of the pipe. These novel features of advantage are attained by the construction of the bracket-wall with suitable projecting flanges for carrying the ends of the pipes and holding same in axial alignment, and by the provision of a peculiarly-formed chambered whcel support made integral with the bracketflanges just mentioned; also,byintegrallyformingacylindrical web extension ofthe bottom ofthe wheelcham her, so as tojointly act as a stiffening-brace and as a drain'connection to carry off water accumulation from said chamber.

A detailed description of these novel features is hereinafter given in the specification and illustrated in the drawings annexed, making a part of same, in which- Figure 1 is a longitudinal section. Fig. 2

is a transverse section of the device in position with wheel-pocket in endelevation, taken on the line a: m, Fig. 1.

Fig. 3 is a view in .QIQJKU. (N0 model.)

section taken on the line 3 Fig. 1. is a crosssection of the cylindrical drain-pipe, taken on line a c of Fig. 2.

In metallic conduits as heretofore constructed the pulley-wheels are situated in the lower portion of the interior of the pipe, mounted in side bearings placed in the walls of said pipe or in shallow pockets, making a part of same, so that a considerable depth is necessary in the conduit to accommodate the pulleys, and a proportionate amount of material is required to provide the requisite space vertically considered, and in consequence of this depth the side walls of the conduit must Fig. 4

be made of increased thickness to properly resist the collapsing impact of earth-bed vertical and lateral, and also the deranging results of frost action. In my improved conduit bracketsupport the web-flange A is stitfened at its outer edgeby a cap flange, E E, that is made continuous, as shown in Fig. 2; also, its T shape in cross section is shown in Fig. 3.

The body A of the bracket is given the form represented in Fig. 2. It is lightened somewhat at the points a a by suitable orifices cut therein. The top portion of the flange E E is made horizontal, and is provided with lugs at each outer end for the retention in place of the string-pieces h h ofthe track. (See Fig. 2.) At an intermediate pointin the width of the webflange A thereisformed a proper-shaped opening in the vertical wall of same, and two flanges, O G, are extended ata right angle to the vertical wall. at this point, so as to form a short open-top tube of a proper circumferential are placed in position in the road-bed this method of connection and adjustment will form a continuous conduitpipe, and hold the adjusted and coupled sections in axial alignment. Immediately below the center of the short chamber formed by the flanges C C, and integral with same, a sub chamber, 13, (see Figs. 1 and 2,) is formed of such relative size as to allow the pulley-wheel H to be properly located therein. This wheel is grooved in the usual manner for the retention and support of the cable, and it is made to revolve upon its a communicating passage to connect the lowest point in the sub-chamber B with a sewer or other proper water-drain pipe. Aninspection of the drawings will show that the disposition of material in the wheel-chamberB produces an inverted hollow hemisphere with four fiattened sides. This double-arched cavity affords the best approved economic form of construction to obtain rigidity in the supportingbracket A and elastic strength to compensate for expansion and contraction of material; also resist vertical as well as lateral pressure or strain on the parts and the disrupting influence of frost. The cylindrical extension below the crown of the spheroidal chamber B is an additional brace to the bracket-flanges A A, and it will be observed that its perforation of the crown or lowest point in said chamber B will effectually drain it of all surface water that may enter from above.

The affixed position of the stationary shaft 1?, upon which the pulley-wheel H revolves, is such in relation to the lower interior surface of the conduit L L, supported above it, that the major portion of the pulley-body is contained in the chamber B, and consequently the vertical depth of the projecting flanges that carry the conduit-pipe L L can be materially reduced. The sectional area of the short chamber formed by the j auction of these flanges O O is also contracted, so as to permit a comparativelysmall conduit-pipe to be used. This is evident, as the space required in conduits in which wheels are located interior thereto is rendered unnecessary by my improved method of constructing the wheelchamber B.

It is obvious from this that a remarkable reduction in amount of material required for of same.

construction is obtained and a consequent economyin cost of manufacturing the conduitpipes effected.

The cylindrical connection for water removal may be attached to a longitudinal underlying drain-pipe, I, (seeFig. 1;) or by suitable pipe-extension the water may be led off to a laterally-located sewer. 7

It is evident that various modifications in the shape of the several parts of my invention may be made without-departure from the spirit I therefore desire sufficient latitude allowed in the descriptive matter, and its relation to the drawings, to permit slight varia tions therefrom to facilitate mechanical execution, or for other necessary causes that may appear.

Having fully described my invention, what I claim as new, and desire to secure by Lelters Patent, is

1. A cable railway bracket shaped substan- .tially as described, and provided with a slot for the passage of the grip, an opening or passageway for the cable, and a chamber below the cable passage-way for a pulley for supporting the cable, substantially as set forth.

.2. The combination, with a bracket for the support of conduit-pipes of cable railways, having two opposite pipe-supporting flanges, and a wheel-chamber made integral with same, of the wheel and its axle, substantially as set forth.

3. In a bracket for conduit-pipes of cable railways, having pipe-supporting flanges and a chambered wheel-support made integral with a lateral flange, the combination therewith of a revolving pulley-wheel, its supporting-axle, and a central drain-pipe, substantially as set forth.

4. A cable-railway bracket shaped substantially as described, and provided with a slot for the passage of the grip, an opening or pas sageway for the cable, a chamber below the cable passage-way for a pulley for supporting the cable, and a drainpipe communicating with the pulley-chamber, substantially as set forth.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
